Answer:
37.32
Explanation:
First, we need to use the standard normal table and find the value of z that satisfies the following
P(Z < z) = 0.38
Therefore z = -0.3
Then, the x value is equal to:
x = zs + m
Where m is the mean and s is the standard deviation.
x = (-0.3)(9) + 40
x = -2.7 + 40
x = 37.3
Therefore, the x value is 37.32
